Description

The TS32MLS64V8D2 is a 64M bit x 64 Synchronous

Dynamic RAM high-density for PC-100. The

TS32MLS64V8D2 consists of 16pcs CMOS 16Mx8 bits

Synchronous DRAMs in TSOP-II 400mil packages and

a 2048 bits serial EEPROM on a 168-pin printed circuit

board. The TS32MLS64V8D2 is a Dual In-Line

Memory Module and is intended for mounting into

168-pin edge connector sockets.

Synchronous design allows precise cycle control with

the use of system clock. I/O transactions are possible

on every clock cycle. Range of operation frequencies,

programmable latencies allow the same device to be

useful for a variety of high bandwidth, high

performance memory system applications.

Note:

1. The minimum number of clock cycles is determined by dividing the minimum time required with

clock cycle time, and then rounding off to the next higher integer.

2. Minimum delay is required to complete write.

3. All parts allow every cycle column address change.

4. In case of row precharge interrupt, auto precharge and read burst stop.

2. If clock rising time is longer than 1ns, (tr/2-0.5)ns should be added to the parameter.

3. Assumed input rise and fall time (tr & tf)= 1ns.

If tr & tf is longer than 1ns, transient time compensation should be considered,

i.e., [(tr + tf)/2-1]ns should be added to the parameter.

Note: 1. OP Code : Operand Code

2. MRS can be issued only at both banks precharge state.

A new command can be issued after 2 CLK cycles of MRS.

3. Auto refresh functions are as same as CBR refresh of DRAM.

The automatical precharge without row precharge command is meant by “Auto”.

Auto/self refresh can be issued only at both banks precharge state.

4. BA0~BA1: Bank select address.

If both BA0 and BA1 are “Low” at read, write, row active and precharge, bank A is selected.

If both BA0 is “Low” and BA1 is “High” at read, write, row active and precharge, bank B is selected.

If both BA0 is “High” and BA1 is “Low” at read, write, row active and precharge, bank C is selected.

If both BA0 and BA1 are “High” at read, write, row active and precharge, bank D is selected.

If A10/AP is “High” at row precharge, BA0 and BA1 is ignored and both banks are selected.

5. During burst read or write with auto precharge, new read/write command can not be issued.

Another bank read/write command can be issued after the end of burst.

New row active of the associated bank can be issued at tRP after the end of burst.

6. Burst stop command is valid at every burst length.

7. DQM sampled at positive going edged of a CLK masks the data-in at the very CLK (Write DQM latency is 0),

but makes Hi-Z state the data-out of 2 CLK cycles after. (Read DQM latency is 2)
